Open source solution to Vietnam landslide map

Landslide risk maps in Vietnam are to be collated and updated via a new open source software platform.

The online mapping system Web GIS is being used to disseminate and share the findings of landslide risk mapping project, which started give years ago, and to allow authorities and local people to add updates.

The Surveying, assessment and partition of landslide risk in mountainous regions of Vietnam project was launched in 2012. So far the Institute of Geosciences and Minerals has completed the map of landslide status in 15 mountainous provinces in the north including Thanh Hoa, Nghe An, Lao Cai, Yen Bai, Son La, Lai Chau, Dien Bien, Cao Bang, Bac Kan, Tuyen Quang, Ha Giang, Bac Giang, Hoa Binh and Lang Son. Assessment and warning zone analysis has been carried out on seven of these areas and data on four of these has been shared with the provinces via the software tool.

According to the Ministry of Natural Resources and Environment, this is the first time these provinces have been able to anticipate landslide in their localities.
